The NAF Duball DL Pocket Valve is installed for safe removal of sand and fine debris out of the process as effectively as possible while maintaining process pressure

NAF Duball DL Pocket Valve is based on the heavy-duty NAF Duball DL valve

The valve is specially designed to withstand extremely tough applications where the media causes a high degree of wear; resulting in less need for maintenance and a longer lifetime

Solid ball in Alloy 6 minimizes maintenance

Easy installation and replacement as a result of the off-center joint face of the valve body
